Mouse allows quick and easy access to many icons and operations on the computer, such as selecting from a list of possible actions (menu), work with Windows and moving files. when you move the mouse, the rubber ball turns and runs two rollers, both associated with wheel with slots. light-emitting diode (LED) sends light through the slits and transducers convert light into an electrical signal. Pressing the button will send additional information to the computer.The main goal of any mouse is to translate the motion of your hand into signals that the computer can use. Let's take a look inside a track-ball mouse:

1. Roller - Roller turns by turning the rubber ball back and forth2. Rubber Ball - The ball is turning when you run the mouse over the surface3. Moving Roller4. Slotted wheel - This wheel with the slots associated with vertical rollers.5. Light emitting diode6. Converter7. Cable coupling8. Plastic housing9. Cable - cable connects the mouse to the computer through input on your computer10. Chip - The chip processes data from the transducer movement and buttons before it transmits them to computer11. Right button - The button pressing their work to encourage the chip and the chip sends signals to the computer12. Roller - This is moved by rotation of Roller balls

1. Wheel with slots - when the wheel rotates, the movement of the slot next to the diode produces light flashes2. Light-emitting diode (LED) - LED sends light through the slits on the outer edge of the wheel3. Converter - Converter code flashes of light into electrical signals.4. Roller Lever - Lever roller transfers spins on the wheel with slits.
